Then to see Roger go out against John Millman. It was like, Federer and Serena Williams are two of the greatest champions of our sport ever, both have had these moments of reality. Will they win again? I want to see Federer go out this way, I want to see him fight for his sporting life.

I want to see him get tired, show everybody that it's not that easy to be a champion. You have to give all even when you are not winning. I hope he keeps going, I think he will, and then I think Nadal and Dominic Thiem. This was just a physical, mental battle.

It was the latest night we had at the US Open That was a huge match, conditions were terrific for three or four days. I actually have never been at the US Open where it has been so hot and humid. That's what US Open is, it's very up and down, players get tired, exhausted, it's the end of the Grand Slam season, but we had a very fresh final today, which was a great ending to these two weeks.'
